GS4A022211JFT Description

The GS4A022211JFT from TT Electronics/IRC is a high-performance 4-resistor isolated network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 2.21KΩ resistance value and ±5% absolute tolerance, this ceramic-based network ensures reliable performance in demanding environments. Its ±50ppm/°C temperature coefficient and 0.1W power rating per resistor (0.4W total) make it suitable for circuits where thermal stability is critical. The SOIC-C series construction features gull-wing termination for secure surface mounting, while the 100V maximum voltage rating and 125°C maximum operating temperature ensure durability in industrial and commercial applications.

GS4A022211JFT Features

• Isolated Circuit Design: Each of the 4 resistors operates independently, eliminating crosstalk in sensitive analog/digital systems.
• Precision Thin Film Technology: Delivers ±1% ratio tolerance for matched resistance pairs, ideal for differential amplifiers or voltage dividers.
• Robust Ceramic Package: The SOIC case style (4.9mm × 5.99mm × 1.45mm) provides mechanical strength and thermal dissipation.
• Wide Temperature Range: Operates from 70°C to 125°C @ derated power, outperforming standard networks in high-heat scenarios.
• Automation-Friendly: 1.27mm terminal pitch and surface-mount compatibility streamline PCB assembly.

GS4A022211JFT Applications

This resistor network excels in:

• Signal Conditioning: Isolated resistors ensure accuracy in sensor interfaces (e.g., thermocouples, strain gauges).
• Medical Electronics: Stable performance in patient monitoring equipment due to low TCR and high voltage isolation.
• Industrial Control Systems: Reliable operation in PLCs and motor drives where temperature fluctuations occur.
• Test & Measurement: Precision ratio tolerance (±1%) suits calibration circuits and instrumentation amplifiers.

Conclusion of GS4A022211JFT

The GS4A022211JFT stands out for its isolated thin-film resistors, ceramic durability, and tight tolerance specifications, making it a superior choice for precision electronics.
